Abstract
Three-dimensional stereophotogrammetry is commonly used to assess volumetric changes
after facial procedures. A lack of clear landmarks in aesthetic regions complicates
the reproduction of selected areas in sequential images. A three-dimensional volumetric
analysis was developed based on a personalized aesthetic template. The accuracy and
reproducibility of this method were assessed. Six female volunteers were photographed
using the 3dMDtrio system according to a clinical protocol, twice at baseline (T1)
and twice after 1 year (T2). A styrofoam head was used as control. A standardized aesthetic template
was morphed over the baseline images of the volunteers using a coherent point drift
algorithm. The resulting personalized template was projected over all sequential images
to assess surface area differences, volume differences, and root mean square errors.
In 12 well-defined aesthetic areas, mean average surface area and volume differences
between the two T1 images ranged from −7.6 mm2 to 10.1 mm2 and −0.11 cm3 to 0.13 cm3, respectively. T1 root mean square errors ranged between 0.24 mm and 0.62 mm (standard deviation 0.18–0.73 mm). Comparable differences were found between the T2 images. An increase in volume
between T1 and T2 was only observed for volunteers who gained in body weight. Personalized
aesthetic templates are an accurate and reproducible method to assess changes in aesthetic
areas.
